I made a chart comparing the capabilities of 15 free Windows fonts at displaying glyphs you might need in Textual Criticism (TC) footnotes, including display of Coptic. The fonts compared are: Cambria Math, Cardo, Antinoou, IFAOGrec, Brill, GentiumAlt, FreeSerifCoptic, DoulosSIL, Andika, Palatino Linotype, Times New Roman, New Athena Unicode, Titus Cyberbit Basic, SBL, and Galilee.
